"Tubular two-chamber liquid dispenser ¹ '

The invention "relates to a tubular two-chamber fluid dispenser for tight insertion into a container opening, the outer one facing away from the inside of the container Area one by tilting the container over an opening located on the meter periphery "from the inside of the container takes up the dosing space to be filled and its inner area facing the inside of the container through it The bottom is closed and a pouring channel to be connected with the outside space and by tilting back of the container from the metering chamber to be filled collects Ir aum.

In a metering device of this type, the metering space is designed as a cylinder ring. The cylinder ring surrounds the The pouring channel is essentially coaxial and - in an overhead position - is facing away from the inside of the container To fill 3 ends and to empty into the collecting space by tilting it into an upright position. at If you tilt it again, the liquid stored in the collecting space will be discharged via the pouring channel; at the same time the dosing space is filled again. Because of the relatively tight The metering device allows only a correspondingly low and highly viscosity-dependent metering speed to. Depending on the viscosity and the ring gap width of the cylinder ring, pressure compensation can also be difficult conditional, inhibited jjTLießbsginn occur. at stiff container and metering walls can prevent this act like an operre.

The invention is based on the object of a possible a few existing two-chamber dispenser components that can be manufactured economically in mass production to create with high dosing accuracy, in which the flow inhibition does not occur and its dosing speed and accuracy essentially independent of viscosity are. The solution according to the invention consists in that the cover surface facing away from the bottom of the for yordosing trained dosing space is closed except for a passage for the pouring channel and that the Dosing space from the collecting space, which is designed as the main dosing space, through a funnel-shaped insert with designed as a pouring channel Funnel drainage pipe is separated except for at least one opening on the periphery of the insert.

With such a structure, the metering chamber has such a large cross section in its essential Toil that the above-mentioned plie inhibition cannot occur. At the same time, the through-opening forms between the dosing chamber and the collecting chamber such a narrow transition between these spaces that a high level of metering accuracy is ensured. In In this context, it should be pointed out that it is advisable to have several through openings, preferably evenly distributed, be provided on the periphery of the insert. In the case of it, it can be advantageous to place the respective passage opening in the form of a from the periphery to the center of the Use to form a tapered notch. The narrow passage opening between the dosing space and the stacking space is formed as it were, the germ for the beginning of the pouring; at the edges of the opening, especially if it is pointed 7orm, any meniscus that may arise will also tear in the case of a relatively highly viscous liquid, so that problem-free dosing is made possible.

According to a further invention, the becomes firm with the insert connected pouring channel in the implementation of the cover surface in the direction of the Rohrlängsaclise mounted displaceably. The funnel drain pipe can be placed in a tubular mouth insert fastened in the cover surface or, e.g. via radially, star-shaped projecting arms, on the inner surface of a cylindrical tubular chamber trained doser outer wall are performed. Such a measure is surprisingly simple created a dosing device that can be preset with regard to the dosing amount.

Finally, it can be advantageous for a quick filling of the metering space if the metering space next to a lateral perforated inflow opening a circumferential Has an annular gap on the meter periphery adjacent to the cover. In the upside down position of the feeder The liquid to be dosed can then be removed from all sides at the same time from the upside-down lid out in the metering chamber until they reach the height of the hole-shaped Inflow opening reached.

Since the dispenser according to the invention in 3refer to his The longitudinal axis is constructed symmetrically, it can be used both for yordosing and for dosing in any direction be tilted. With a suitable arrangement of its inlet on the container side, the dosing device allows a complete Container emptying closed. Moving parts such as balls are not required for dosing, a single-handed operation is easily possible. Finally, the invention requires The dispenser does not have to manufacture complicated molded parts as it essentially consists of just one cylinder with top and bottom cover and a funnel that can be mounted in the cylinder so that it can be moved if necessary.
